Hulk the Mastiff Mix and Chihuahua! Best Friends!

THE world’s biggest pitbull has struck up a bizarre friendship with a tiny chihuahua more than thirty times smaller than him. World-famous Hulk, who shot to fame last year in a viral video, weighs in at 181lb while tiny Mami weighs just five pounds. But the difference in size and power hasn’t stopped them becoming firm friends who spend all day together at their home in New Hampshire, USA. DarkDynastyK9s
